Tuesday, September 1

The global bond sell-off intensified, led by the U.S. long end. The 10-year Treasury yield reached about 4.78%, its highest level since early 2025, while the 30-year rose to roughly 5.27%. Market pricing for a September Federal Reserve hike climbed to approximately 70–75%, up sharply from the mid-30s before Chair Kevin Warsh’s hawkish comments.

The move was not confined to Treasuries. Japan’s 10-year yield breached 3% for the first time in 30 years, and Australia’s 10-year yield reached about 5.18%, a roughly 15-year high. That breadth points to a repricing of duration and term risk rather than a purely U.S. policy adjustment. Equities weakened, transports underperformed, the dollar firmed, and the yen approached 160 per dollar, reinforcing pressure on rate-sensitive and emerging-market assets. The key shift is that additional Fed tightening is increasingly treated as the base case, tightening global conditions before any new policy decision.

Brent crude held around $91–92 a barrel after a prior-session jump of roughly 2.7%, while WTI traded near $86–88 and some quotes showed a 2.55% daily gain. The catalyst was a sharp escalation in U.S.–Iran hostilities, including attacks involving shipping around the Strait of Hormuz and an Iranian ballistic-missile strike on a U.S. Marine base in southern Jordan.

The market response matters less for the day’s percentage move than for the route at risk. Drone activity and cargo-ship attacks revived concern over Gulf flows, creating an energy risk premium that compounds the pressure from higher global yields. Transport shares lagged in the United States, while oil-sensitive sectors such as aviation and paints came under pressure in India. President Donald Trump said the strait was in “extremely good shape,” but crude pricing continued to reflect disruption risk rather than that reassurance. The combination raises the threat of weaker growth alongside renewed inflation pressure.

Germany formally attributed a foiled explosives-laden drone plot at Leipzig/Halle Airport to Russia, raised its threat assessment to “high,” and ordered the closure of Russia’s consulate in Bonn and the Russian House in Berlin. Moscow rejected the accusations. The measures mark a further deterioration in Germany–Russia relations, with potential consequences for sanctions, trade, and European security policy.

The diplomatic escalation came as Russia launched another missile-and-drone wave against Kyiv and surrounding areas, killing at least 12 people and damaging residential and civilian infrastructure. Those attacks maintain direct pressure on Ukraine while the German response broadens the confrontation into European institutions and domestic security. Russia’s finance minister, Anton Siluanov, meanwhile appeared at G20 finance talks in North Carolina after an invitation from the Trump administration, underscoring the contradictory mix of confrontation and selective engagement. For markets, the immediate channel is a higher geopolitical premium across European energy, defense, and sovereign-risk exposures.

The Federal Trade Commission, joined by 22 states, sued Amazon alleging that the company secretly manipulated advertising auctions and raised advertising costs by more than $20 billion. The case targets a high-value profit engine rather than only Amazon’s retail marketplace, making the potential valuation implications broader than a conventional consumer-protection dispute.

The allegations add headline and legal risk to a megacap technology name even as AI-related tech remained relatively resilient during the broader equity sell-off. They also sharpen the regulatory question facing digital platforms: whether auction design and marketplace control allow firms to extract higher monetization from advertisers while limiting competitive alternatives. No major tech IPO or megadeal offset that development in the available news. The immediate market issue is not a reported financial penalty, but the possibility that enforcement pressure eventually affects advertising economics, platform practices, or the way investors value large-cap technology cash flows.
